- the antenna 29 is composed of antenna elements 121 and 122 integrally formed with a bar-shaped support member 110 made of a synthetic resin.
- the support member 110 is provided with a concave portion 111 to avoid interfering with the strap wall part 23 b .
- the antenna element 121 is located in such a manner that it straddles a gap between the edge portions of side walls 112 a and 112 b of the concave portion 111 to avoid interfering with the strap wall part 23 b.
- the support member 110 is divided, at the concave portion 111 , into two parts in the length direction (the direction of arrow M 1 ), except for a connection portion 113 that is a part of the support member 110 in the width direction.
- the antenna element 121 is formed in such a manner that a metal wire 121 f constituting the antenna element 121 straddles over the concave portion 111 .
- the side walls 112 a and 112 b of the concave portion 111 are fitted into the strap wall part 23 b ; thereby positioning of the antenna 29 in the length direction is made.
- the antenna 29 is located in the rear case 12 in such a manner that the main parts of the antenna elements 121 and 122 , i.e., the front-side parts thereof, are positioned on a surface away from the printed circuit board 25 located in the front case 11 .
- the antenna 29 has a bar-like shape with an approximate rectangular cross-section.
- the antenna 29 is formed by an insert molding process using a synthetic resin such as an ABS resin, the antenna elements 121 and 122 , and a feeder electrode 120 , each of which has been formed into a predetermined shape.
- Holes 116 which have served to support the antenna elements 121 and 122 during the insert molding process, remain in the support member 110 .
- the entire shape of the support member 110 corresponds to the shape of the inside surface of the rear case 12 .
- the support member 110 has, at an end portion opposite to the feeder electrode 120 , a projection 115 that engages with a wall part of the rear case 12 or other electronic components BH when the antenna 29 is fitted into the rear case 12 ; thereby misalignment between the antenna 29 and the rear case 12 is prevented.
- the antenna elements 121 and 122 are formed by a press molding process using a metal material such as beryllium copper.
- the feeder electrode 120 is obtained by plating, with gold, the surface of the resultant produced by a molding process using phosphor bronze.
- the feeder electrode 120 is provided with a mounting hole 120 a through which the screw 19 for coupling the front case 11 and the rear case 12 together passes. Thereby, the antenna 29 is entirely sandwiched between the front case 11 and the rear case 12 , so that the antenna 29 is fixed therebetween.
- the antenna element 121 is composed of strip-like metal wires 121 a - 121 v extended and bent in the stated order.
- the antenna element 121 is to transmit and receive radio waves, for example, in 2 GHz frequency band.
- the antenna element 122 is composed of strip-like metal wires 122 a - 122 c , which have a width larger than that of the antenna element 121 , extended and bent in the stated order.
- the antenna element 122 is to transmit and receive radio waves, for example, in 800 MHz frequency band.
- the main parts of the antenna elements 121 and 122 are formed on the front face MS and the top face MJ of the support member 110 .
- the antenna 29 is located inside the rear case 12 in such a manner that the front face MS and the top face MJ of the support member 110 are closest to the inside surface adjacent to the upper side 12 a of the rear case 12 (see FIGS. 15A-15C ).
- the main parts of the antenna elements 121 and 122 are located away from the printed circuit board 25 and the electronic components BH mounted thereon. This reduces the influence of the printed circuit board 25 and the electronic components BH inflicted on the antenna 29 , and also reduces the influence of radio waves emitted from the antenna 29 inflicted on the printed circuit board 25 or inflicted on the electronic components BH. Hence, the antenna is configured to exhibit good performance.
- the antenna element 121 is formed, on the front face MS and the top face MJ of the support member 110 , to have a meandering shape and extends along the length direction. Further, the antenna element 121 slightly projects, like a bridge, beyond the concave portion 111 on the side of the back face of the rear case 12 to avoid interfering with the concave portion 111 .
- the antenna element 122 is formed, on the front face MS and the top face MJ of the support member 110 , to have a meandering shape and extend along the circumferential direction while winding around the support member 110 .
- the antenna 29 is a dual band antenna.
- the antenna elements 121 and 122 are formed to have the shapes and length as described above, and conform to standards of, for example, receiver sensitivity, radiation efficiency, directivity, and impedance in a predetermined frequency band.
- the antenna 29 in the embodiment described above even if a projection is provided at the center of the rear case 12 due to the strap retaining portion 23 , it is possible to place the antenna 29 so as to avoid interfering with the concave portion. Further, positioning of the antenna 29 in the length direction may be made by fitting the side walls 112 a and 112 b of the concave portion 111 into the strap wall part 23 b , which facilitates mounting of the antenna 29 on the rear case 12 .
- the antenna 29 may be a monopole antenna, a dipole antenna, an inverted-F antenna, an inverted-L antenna, and various other antennas.
- the overall structure of the antenna 29 , the antenna elements 121 and 122 , the printed circuit board 25 , the casing KT, or the mobile phone 1 , or the structures of various portions thereof, the constitution, the shape, the size, the molding method, the production method, the arrangement, the quantity, the material, the position, the frequency, and the like may be altered as required in accordance with the subject matter of the present invention.
- the description is provided of the folding mobile phone 1 .
- the embodiment is also applicable to a non-folding mobile phone, and a variety of other folding or non-folding mobile terminals such as PDAs and lap top computers.
